47. you and a friend are picking up trash on a beach.
you fill 2 bags with trash in 28 minutes. your
friend fills 3 bags with trash in 48 minutes. who
fills bags with trash faster? how much sooner
will the faster person fill 7 bags with trash?

You would do it faster

Step-by-step explanation:

48/3 is 16 minutes per bag

28/2 is 14 minutes per bag

You fill the bags faster. You will finish filling the 7 bags of trash 7 minutes sooner than your friend.

Step-by-step explanation:

Divide 28 minutes by the 2 bags of trash. You fill 1 bag of trash every 14 minutes. 28 ÷ 2 = 14

Your friend fills 1 bag of trash every 16 minutes.

48 ÷ 3 = 16

7 bags × 16 min. = 105 min.

7 bags × 14 min. = 98 min.

105 - 98 = 7 minutes
